Inhaling salty steam for lung MAC infection
This trial studies whether inhaling hypertonic (very salty) saline helps treat nodular-bronchiectatic lung disease caused by Mycobacterium avium complex (MAC).

Tenofovir to stop liver disease in mild hepatitis B
This trial tests tenofovir alafenamide (a hepatitis B antiviral medicine) to see if it can prevent liver disease from getting worse in people with chronic hepatitis B who currently have stable (normal) liver blood tests and low virus levels. It may help lower the chance of developing serious liver complications over time.

Mobile rehab program with interval exercise after COVID-19
This trial tests a coach-supported, phone-based rehabilitation program that includes high-intensity interval-style exercise for people recovering from COVID-19 after a hospital stay. It may help improve breathing, strength, and walking by providing structured exercise at home.
Birmingham, AlabamaAges 18 years+ - NCT05218356RecruitingPhase 2
Codivir trial for hospitalized moderate COVID-19
This trial tests whether Codivir can help people hospitalized with moderate COVID-19 recover better than a placebo (inactive pill). It will compare outcomes while participants receive standard hospital care.
Paulo Prata, Barretos/SP/BRAAges 18–75 - NCT05219110Recruiting
More fluids for children sick with toxin E. coli
This study looks at whether giving extra (hyper) fluids early helps children with a high-risk E. coli stomach infection. The goal is to improve outcomes by supporting the kidneys during the illness.
Birmingham, AlabamaAges 9 months–21 years - NCT05224401RecruitingPhase 3
Oral antibiotic step-down for ESBL bladder infections
This Phase 3 trial tests whether switching from short-term IV antibiotics to an oral antibiotic combo is safe and effective for ESBL urine infections. It may help you avoid staying on IV antibiotics as long, if your bacteria are the right match.
HelsingborgAges 18–130 - NCT05225402Recruiting
Testing blood-flow measurements in ICU shock patients
This trial studies how blood flow and organ “perfusion” look in ICU patients who are struggling with infection and low blood pressure. It may help doctors better measure and manage shock by comparing hemodynamic readings during standard treatment.
Hvidovre, CopenhagenAges 18 years+ - NCT05227937Recruiting
Single-dose antibiotic for uncomplicated bladder infection in the ER
This study tests whether giving one dose of amikacin in the emergency department is practical and safe for treating uncomplicated bladder infections. It also looks at how patients do after treatment over the next 3, 7, and 30 days.
Brooklyn, New YorkAges 14–110 - NCT05228691Recruiting
Study Long COVID symptoms in the Canary Islands
This study looks at how common long-term COVID symptoms are in people across the Canary Islands. It may help researchers better understand who is affected and what symptoms last, which can support future care.
